大般涅槃經義記 6.345

6.345

破入獄中，句別有三：一以頻婆現受善報及以惡果明王不定、二以王不定成殺不定、三以殺不定破定入獄。

In refuting falling into hell, there are three distinct phrases: first, through Bimbisāra's presently receiving good retribution as well as evil fruit, it clarifies that the king is indeterminate; second, through the king's indeterminacy, it establishes that the killing is indeterminate; third, through the killing's indeterminacy, it refutes definitely falling into hell.
